Hmmm.... to be ugly, you could cut the wire in 1/2 and then splice a longer piece to it.
Now, this may not work because the connectors wont probably match but you could try for a RC Servo Extension cable. They are cheap on ebay - I got 10 - 18in extension cables for about $5 with free delivery from a US Company. It took a week to get it shipped to me. In fact, this is who I got it from:

Checking out prices, I seen that they go up and down, from $2 for 5 cables from China with free shipping to $1.50 for a single cable with $3 shipping. Go figure.
But again, the header/connector may not be right but one can switch the cable connectors. That's up to you.
